No one knows exactly what surprises the future has in store for us. The surprises of the past, however, are a lot less mysterious. Today, we want you to cast an eye backwards and tell us about the biggest surprise that the past you never would have believed was in the future.

Was it the invention of tech that you thought was still years away (hey, past me, soon we'll have cameras built into our phones, which, by the way, will be incredibly small!)? Maybe it's the ways in which we use that tech (but, sorry, we'll mostly just use them to take close-range photos of own faces)? Or maybe it was just something from you own life.

Tell us now in the comments about all the things the past you never would have expected to see, but did.
